“In this day and age, most companies use electronic accounting systems and pay accounts electronically, which can make them susceptible to business email compromise scams,” Det Supt Katsogiannis said.

“We would encourage all businesses to develop systems to combat against scams, including scrutiny of email requests to transfer funds or change account details, and standard procedures to follow to protect against business email compromises.

“While there are many variables, generally, the perpetrators will ‘spoof’ or compromise corporate executive or employee email accounts and send email requests to an accounts payable employee for an electronic funds transfer.

“Staff should be suspicious about these types of requests, and if they take the time to verify the authenticity of the email, whether it be via phone or a fresh email, they can potentially prevent the compromise.

“That said, we still encourage anyone – corporate or personal – who have been a victim of email compromise to report it to police,” Det Supt Katsogiannis said.

ABF Detention Operations Commander Bill Ries said the ABF is committed to working with state police counterparts to ensure the safety and security of the detention network and to stamp out criminal activity.

“The ABF has been making the case for some time for powers to remove phones from detainees within immigration detention centres, many of whom have had their visas cancelled for serious criminal offences,” Commander Ries said.

“We know phones can be used to coordinate escape efforts, as a commodity of exchange, to facilitate the movement of contraband, to convey threats and, in this case, to organise significant criminal activity outside our centres.

“The continued use of phones in detention poses a significant threat to our staff, to detainees and the broader community.”
